Genius idea for the new Mac Pro

I recently trotted upon this when reading a windows 8 article and what I'm most interested in this concept is this

"You could add a connector on the bottom of the Mac Pro to make it super elegant or just a simple 90 degrees Thunderbolt connector."

Now this got me excited, you could add a hard drive, extra ports or even a larger speaker the possibility are endless. Although not too many or I could see pictures of Mac Pro's toppling off desks from around the world.
